Summary and conclusions
The multiplication of cytopathogenic strain of Newcastle disease virus in monolayers of chick embryo cells was studied. The latent period in the growth cycle of this virus was found to last 8–9 1/2 hours, followed by a period of rise lasting 3–4 1/2 hours. The average yield of virus per cell in the tissue culture was found to be approximately 300.
